IMPROVEMENT lN SHELVING FOR -STORES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it-knownvthat I, RIeHARDllIUnnocn, of Baltimore, in the county ot'Baltimore and State oi' 'Maryland, have invented a new and improvedShelving forl Stores; and I do hereby declare theV following to bc afull, clear, and exact description of thesame, reference being had tothe accompanying drawing making a part same, in order that the surfacesot' the walls may -be utilized for shelving clear to the ceilings.

lhe invention consists ot' upper sections ot shelving made movablevertically, so Vthat the salesman may draw thc goods down to himselfinstead of' going up to the goods, each movable section ot' shelvingbeing provided with a counterl'mlance, or one section being hung,- inopposition to another, and latch mechanisms being provided for thepurpose ot' preventing a section of shelving, as itsweight decreasesbyreason of the removal otgoods therefrom, from being drawn upward bythe counterbalancc before the salesman is readyto let it risc.

Referring to thc drawing- A is a case containing shelves divided intoinnnovable sections a.

bfarc movable sections of shelves ruiming in grooves in the inner sidesofthe case A, and extending in front of the same,

The sections b are each connected, as shown in fig. 2, by cords c,running over sheaves d hung-to; the top et' the case A,.wi'th an arm,0,. that extends upward, in rear ofthe sh elves a, from acounter-weight, f, which may be either" solid or may consist of a vesselfor containing liquids.

By-means of the counter-weights f the sections I) may be raised to thetop of tl1ecasc,so as not to cover the `front of the vsections 11. A

When the salesman has occasion to exhibit goods .stored in either of theupper sections of. shelving, hc

has simply todraw the same down to within reach.

For drawing' the" "sections I) down, two dite'rent mechanismsv areshown. One mechanism consists of the bar h, fig. 1, which hangshorizontally below the section a, being connected therewith by cords 0',and serving as a handle.

A cord, 1.-, is also attached tothe barh, and, passing through an eye,l, in the bottom of the section b, is attached at its'other extremity toa latch, m, that is pivotcd to the back side ofthe section, and ispressed, by a spring, n, into a notch formed iu the inner side et' thecase A. l

When thc section is drawn down the latch m holds 0n pulling the bar h,the cord 7c withdraws the latch from its notch, so that it presents noobstacle to the descent otthc section.

The second mechanism consists ol'a lever, o, iig. 1, pivoted beneath thesections ot' shelving a, and connected at its lower end with a cord, fr,whose other eX- tremity is attached to the lower side of the section b.

On turning the lever' o toward the perpendicular, a pin, projectingbackward from near its upper end, strikes the cord r, and causes thesame to. draw the section 7) downward.` l

The cord 0'- passes between'plates t, fig. 4, that are supportedhorizontally in a. bracket, u, attached beneath the base-board B of thesections a.

The plates t are connected with a'lever, c, by which they may be drawn,to a degree, out of the bracket a.' On thus drawing out the plates t,the cord r is released from the clamping of the plates, and allowed tobe operated by the lever,

On releasing the lever lv, the springgv presses the plates t intothcbrackct il, causing them to clamp and hold the cord, and thuspre-vent the counter-weight` from. raising the section l).

:The sections b may be hung in opposition, so Aascach to act as'thccounter-weight of the other.

'lhc sections a may also be made movable, and operate a'scounter-weights to the sectionsb.

Having thus described my invention,

What I claim as new, and desire to secure byfLet-V vters Patent, is

1. A case of shelves, provided with sliding sections,I combined withcounter-weights,.substantially as described.

2. The arrangement of theI levers o v, cord fr, plates t, and bracket n,as specified.
